Specification of Letters Patent.

Patented March 5, 1907.

Application iiled November l5, 1905. Serial No. 287,450.

To (LZZ whom, it may con/cern.-

Be it known that we, RAY S. WHIPPLE, a citizen of the United States, andJOHN A. OLEssAK, a subject of the Emperor of Austria, and both residentsof Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented a new and Improved Combined Turning-Tool andCalipers, of which the following is a full, clear, and exactdescription. This invention relates to an improved means for turningwood to exact diameters, and has for its object to provide novel detailsof construction for a wood-turning tool and for a caliper attachmentthereon that are adapted for cooperative use, affording a gage as wellas a turning-tool, whereby a piece of material may be rapidly turned toa desired diameter at one operation.

The invention consists in the novel construction and combination ofparts, as is hereinafter described, and defined in the subjoined claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specihcation, in which similarcharacters of reference indicatecorresponding parts in all the iigures.

Figure 1 is a side view of the improved combined turning-tool andcaliper. Iiig. 2 is a partly` -sectional side view of the same. Fig. 3is' a top view of the improvement, and sectional Fig. 4 is an enlargedtransverse view substantially on the line 4 a in F ig. 3.

The handle-bar 5 employed consists of an'j elongated metal body, mainlyrectangular in cross-section, having the central longitudinal l slots aand 11 therein, the former being of greater width than the latter. Therear end portion 5a of the bar is rendered cylindrical l and is axiallyperforated. On the cylindrical end portion 5EL of the handle-bar isformed an external thread upon which is screwed the forward end of aninternall -threaded thimble 6, into the rear end of which the forward lend of a tubular shank 7 is screwed, whereby the shank is held extendedcentrally from the l rear end of the handle-b ar. Upon the shank 7 apreferably wooden grip-piece 8 is mounted, which receives at its forwardend an adjacent end of the thimble 6. In the hollow shank 7 anadjusting-rod 9 is inserted and I passes loosely through the axialperforation l in the part 5a of the handle-bar and also between the sidewalls of the slot a. The adjusting-rod is cylindrical and is externallythreaded from the forward end thereof for about half its length, asindicated at b in E ig. 2. Upon the threaded body of the adjusting-rod 9two nuts c c are mounted and jammed together at a point which willlocate these nuts as a iixed collar on the rod 9 between the rear end ofthe portion 5a and the front end of the hollow shank 7, thus preventingendwise movement of the adjustingrod, but permitting its free rotation.A thread is formed on the rear end of the hollow shank 7, and upon saidthread is screwed a circular collar d, said collar bearing upon the rearend of the grip-piece 8 and securing it from endwise movement on theshank, as shown in Fig. 2. The rear end of the adjusting-rod 9 isthreaded, and upon said thread a circularly-edged thumb-piece 10 isscrewed, having a loose engagement with the collar d. Upon theprojecting end of the adjusting-rod 9 a jam-nut eis screwed into closeengagement with the thumb-piece 10, thus adapting the latter forrotating the rod when manipulated, and to facilitate the rotatablemovement of the thumb-piece 10 its periphery is milled or roughened, asshown, said periphery projecting slightly outside of the grip-piece topermit it t0 be grasped readily.

Upon the handle-bar 5, over the slot 11, a slide 12 is mounted, adepending` lug 12a at the rear end of said slide fitting loosely intothe slot a. In the lugl 12@L a threaded hole is formed, wherein theforward end of the adjusting-rod 9 is screwed, and on the extremity ofsaid rod that projects through the lug a nipple f is formed, that isseated in a matting socket formed in the cross-b ar 11a of thehandle-bar between the slots a and 11 thereof. A clamping-bolt 13 isprovided for locking the slide 12 in place, said bolt having a beveledhead g, that passes through the slot 11 of the handle-bar and alsothrough a perforation in the slide near the forward end of the latter.The lower edges of the slot 11 are beveled to provide a countersink onthe block 11 for the reception of the bolt-head g, which is thus adaptedfor seating in the slot, having its fiat head-face flush with the lowersurface of the handle-bar, as appears in Fig. 2, said bolt extendingthrough the slide 12 TOO sufficiently to receive a milled nut 13, whichby rotatable movement serves to slide stationary on the handle-bar 5 atany point of slidable adjustment desired.

A cutter-bit 14 is securable on the lower surface of the handle-bar 5 byscrews 15,

assed through perforations in the stock of the bit and screwed intothreaded perforations in the cross-bar 11aL and the forward end 11b ofthe handle-bar, as shown in Fig. 2 The nose 14a of the cutter-bit mayhave any preferred form best adapted for cutting wooden material thatfor the manufacture of an article by turning is held and rotated atproper speed in a wood-turners lathe. As shown, the nose of thecutter-bit is in the form of a flattened gouge that is a common shapefor a wood-turning chisel.

On the forward end of the slide 12 a curved caliper-leg 16 is mounted byscrewing one end of the leg into a tapped hole in the slides, said legthat `curves upward and forward from the slide preferably terminating atthe forward end in an outwardly-bent nger 16a.

On one side of the handle-bar 5 a graduation h is formed, being a scaleindicating inches and fractions thereof, and upon the adjacent side edgeof the slide 12 an indicatorfinger h is formed or secured, which by itsposition when moved over the scale indicates the degree of reduced spacebetween the finger 16' and the cutting edge of the nose 14a, the maximumdistance being shown in the drawings.

In using the improvement the operator holds the tool upon a lathe-restwhile the material to be operated upon is rotating rapidly in the latheand applies the cutter-bit nose 14L to the right-hand end of thematerial, that of course is rotating rapidly toward the cutter-bit. Bymoving the cutter-bit toward the end of the billet of wood the bit willcut away the excess of material, and the contact of the 'finger 16aoppositely upon the turned material will serve as a caliper-gage toindicate the diameter of the cylindricallyturned body that results fromthe turning operation. Obviously drawing the caliperleg 16 toward thecutter by manipulation of the thumb-piece 10 will correspondingly reducethe distance between the 'finger 16a and the cutting edge of the bit 14,so that cylindrical billets of any diameter within the capacity of thetool may be quickly and accurately turned. if variations from acylindrical form are desired, the tool maybe so held upon the lathe-restthat while it is cutting the material the thumb-piece 10 can bemanipulated with one hand, so as to slide the caliper-leg toward or fromsaid thumb-piece and correspondingly alter the form of the finishedproduct.

Having thus described our invention, we claim as new and desire tosecure by Letters Patenthold the comprising a 1. combined turning-tooland calipers,
